Heartbeat Spectrum // Resonant Pattern | Valentine's Day Spiral Notebook · Seasonal Collection
$24.99
Heartbeat Spectrum explores the idea that love is not a symbol, but a signal.
This spiral notebook translates rhythm into form, layering concentric motion and tonal contrast into a composed visual cadence that feels both emotional and analytical.
The Resonant Pattern is structured yet alive. It reads like a waveform captured mid-beat, repeating with intention rather than decoration. Designed for writers, planners, and thinkers who appreciate restraint, this notebook brings architectural clarity to personal expression.
Perfect for Valentine’s Day, yet timeless enough to live on your desk long after the holiday passes.
